When you feel a slight restriction of your airway,causing you to make a deliberate ,yet somethow, subconcious effort to swallow your saliva hard. At which time you sense an amount of phlegm being foced down your esophagus, after this awakening of your "being" you feel hardened surfaces on said phlegm, reminding you of a raisin or stale gummybear. What you just ingested was a "schnozberry".
